Protection Module for DEHNrail modular
Pluggable protection module for Type 3 SPDs
Type 3 Surge Arresters
• High discharge capacity due to powerful zinc
oxide varistor/spark gap combination
• High reliability due to "Thermo Dynamic
Control" disconnector with dual monitoring
• Energy coordination with other arresters of the
Red/Line product family
• Easy replacement of protection modules without
tools due to module locking system with
module release button
• Operating state/fault indication by indicator
flag in the inspection window
• The plug-in protection module can be replaced
without the need to de-energise and without
removing the distribution board cover
• Vibration and shock-tested in accordance with
EN 60068-2
For protecting the power supply circuit of industrial electronics equipment
against surges in switchgear cabinets. For installation in conformity with
the lightning protection zones concept at the boundaries from 1 – 2 and
higher.
